Since a few months back I'm battling dino's in my 25g coral-filled reef. I was making some headway with dosing ATI Nutrion N and P per the calculators instructions, but now both Nitrates and Phosphates have bottomed out again and the dino's are growing stronger, which means I will have to increase the dosing amount.
While no dinos have cropped up in my old 15g reef, the nutrients have now bottomed out there too for the first time, despite broadcast feeding once a day with coral foods and feeding flakes to my clown whenever he's hungry, so I'm now having to start dosing there too.
I feel like I feed so much in my tanks, but it never seems to be enough, compared to my first 10 years in the hobby which were a constant struggle against high phosphates. Is nutrient supplementation really inevitable with mature grown-in reefs? Crazy thing is these reefs have no mechanical filtration of any sort, no skimmer, no particle filter, zip. The only thing I do is weekly water changes, which I can't really get away from due to allelopathy.
